MACHENE FOR ROLLING RODS DR WlRE.

SPECIFICATION forming part of Letters Patent No. 599,336, dated February 22, 1898.

Application filed February 3, 1897. Serial No. 621,758. (No model.)

To coZZ whom it may concern.-

Be it known that I, ABEL KENWORTHY, a citizen of the United States, residing at Water bury, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Machines for Rolling Rods or \Vire, (Case A;) and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will en- IO able others skilled in the art to which it appertains to make and use the same.

My invention relates to the manufacture of rods or wire, and has for its object to produce a machine for reducing rods and wire I5 by rolling which shall be simple and easy to operate and through which each pass of the rod or wire results in two reductions and elongations instead of one and the passes being made very rapidly, thereby greatly decreasing the cost of productiona machine, in brief, which will produce the highest grade of wire at reduced expense.

With this end in View I have devised the novel machine of which the following description, in connection with the accompanying drawings, is a specification, letters and numorals being used to designate the several parts.

Figure 1 is a side elevation of the machine complete; Fig. 2, an end View as seen from the right in Fig. 1; Fig. 3, a partial end View as seen from the right in Fig. 2; Fig. 4, a partial end view as seen from the right in Fig. 3; Fig. 5, an enlarged fragmentary plan View illustrating the relative position of the pairs of reducing-rolls, the guides, and the coiling device; Fig. 6, a section on the line w a: in Fig. 5; Fig. 7, a section on the line y g in Fig. 6; Fig. 8, a section on the line z 0 in Fig. 6; Fig. 9, an end view of the last guide as seen from the position of the second rolls; Fig. 10, a section on. the line 3 s in Fig. 6 5 and Fig. 11 is a View of the wire, illustrating the operation of the two pairs of rolls.

5 1 and 2 denote driving-pulleys on drivingshafts 3 and 4:. I have not shown the belts running over the driving pulleys, as the manner in which the pulleys are belted up is not of the essence of my invention.

5 denotes the floor, and 6 the bed, of the machine, which is supported by legs 7, resting on the floor. It will be noticed that drivingpulley 1 is below the level of the floor and driving-pulley 2 is partially below the level of the floor.

The essential feature in this machine is that I reduce rods or-wire by passing the rods or lengths of wire between two pairs of rolls, both of which are driven. I thus perform two reducing operations at each pass of the rods.

For convenience in description I will use the term rod, although it will of course be understood that in the shops the term wire is ordinarily used after the rods have been reduced to a certain diameter.

In practice my novel machine is adapted for use in reducing either large or small rods or wire. As the length of the rod is very much increased by its passage through the first pair of rolls, it is obvious that the second pair of rolls must run at a higher rate of speed than the first pair of rolls. It is fur therrnore obvious that the relative speed of the two pairs of rolls must be so regulated that the first pair of rolls will not push the rod ahead faster than it can be taken up by the second pair of rolls, otherwise the tendency would be to upset the rod more or less, and friction would be caused, which would consume power, and, furthermore, that the speed of the first pair of rolls must be great enough relatively to the speed of the second pair of rolls so that the rod will not drag, but will pass freely to the second pair of rolls.

In my present machine I effect the desired result and avoid extreme delicacy of adjustment and frequent changes in the speed of the pairs of rolls by placing a friction-clutch A upon driving-shaft 3, by which the first pair of rolls is driven. This clutch I do not consider it necessary to describe in detail, for the reason that any'ordinary friction-clutch may be used. It is sufficient for the purposes of this specification to say that the clutch is provided with adjusting devices 8. The action of this clutch in practice is automatic; but should the rod drag in the first pair of rolls more tension may be put upon the clutch to cause the first rolls to feed the rod along faster. On the other hand, if the I00 first rolls are crowding the second rolls by feeding the rod along faster than it can be .meshing gear-wheels 11 11.

taken up by the second rolls the tension of the clutch may be reduced by means of the adjusting devices, so that the first rolls will not feed the rod faster than the second rolls can take it up.

I have found in practice that the clutch when once adjusted seldom requires to be changed, but will adapt itself automatically to various grades and qualities of rods or wire. In practice one pair of rolls is arranged vertically, the other pair horizontally. It of course makes no difference whether the first rolls are vertical or horizontal. I have shown in the present machine the first pair of rolls as arranged vertically and the second pair horizontally.

9 9 denote the first rolls, which are carried by vertical shafts 10 10, which carry inter- One of these shafts carries a bevel gear-wheel 12, which meshes with abevel-pinion 13 on shaft 3. The shafts carrying both pairs of rolls are ordinary jointed shafts, the upper boxes (not shown) of these shafts lying in a casting 14, and the boxes of one shaft (the right shaft 10, as seen in Fig. 1) are made adjustable in this casting by an ordinary adjusting device, which I have indicated by B. This adjusting device being in common use is not thought to require description in detail, it being sufficient for the purposes of this specification to say that the operator simply manipulates a hand-wheel 15 to move the boxes in or out, as may be required in casting 14. This adj ustment is of course necessary when the size of the rod or wire being operated upon is changed. Either pair or both pairs of rolls may or may not be grooved, as preferred.

16 16 denote the second rolls, which are carried by jointed horizontal shafts 17 17, which carry intermeshing gear-wheels 18 18. One of these shafts carries a gear-wheel 19, which meshes with a pinion 20 on drivingshaft 4.. j

21 21 denote pairs of boxes, one pair only being shown, (see Fig. 2,) by which the rightends of shafts 17 are carried, these boxes lying in castings 22 22. The boxes which carry the upper shaft are made vertically adjustable in the casting by means of an ordinary adjusting device 0. This adjusting device is substantially like adjusting device B. In the present instance I have shown the shafts of this adjusting device as provided with squared ends 23 to receive a wrench. To adjust the upper roll up or down, as may be relarged scale the rolls and the guides by which the wire is conducted while passing through the rolls. D indicates the first guide, E the second guide, and F the third guide. Guide D is secured in opening 24 in casting 14. For

the sake of clearness this guide is removed in Fig. 1. The guide is directly in front of the first rolls. The wire is passed into the guide at opening 25, then between guide-rolls 26, and along a trough 27 to the first rolls. Guide E lies between the first and second rolls. The opening therein tapers in the horizontal plane toward the second rolls, as shown in dotted lines in Fig. 5 and in the sectional views, Figs. 7 and 8. Guide F lies between the second rolls and the coiling device, which I shall presently describe. This guide tapers slightly in the vertical plane, as shown in Fig. 6, and one side wall thereof is formed by a spring 28. (See dotted lines, Fig. 5.) The action of this spring is to throw the rod against the opposite side wall of the guide, which is so placed as to conduct the wire into the grooves of the coiling-rolls.

G denotes the coiling device, which is of ordinary construction and does not require description in detail. The device consists, essentially, of three grooved rolls, which are indicated by 29. These rolls are operated by means of a belt (not shown) passing over a belt-pulley 30 on a shaft 31. Motion is com municated from this shaft to the coiling-rolls by means of a train of gearing II of ordinary construction. (See Figs. 3 and 4.) The rod or wire is curved upward by these rolls and passes through an opening 32 in a shield This shield lies outside of the coiling-rolls, the metal at one side of the opening being curved inward, as at 31 in Figs. 2 and 3, so as to receive the metal upon its surface and guide it over a bracket 35, fixed to the outer side of the shield upon which the rod or wire is coiled, the straight portion of the shield (indicated by 36) acting to prevent the end of the rod or piece of Wire as it is being coiled on the bracket from engaging the coilingrolls again.

In using this machine no primary reducing or pointing of the ends of the rods is required. The operator simply seizes the end of each rod and passes it into guide D, the end of the rod entering opening 25 and passing between guide-rolls 26 and engaging the first pair of rolls 9 9. These rolls instantly pick up the rod and reduce it, the rod, after passing the rolls, being carried by these rolls through guide E and into engagement with the second rolls, which pick up the rod and again reduce it. The second rolls, after reducing the rod, carry it along guide F and pass it to the coiling device, which is driven independently of either pair of rolls. The exact details of construction of the guides are not of the essence of my invention. The second guide, as already stated, (guide E,) is in the present instance tapered in the horizontal plane, so as to conduct the wire directly into the grooves in the second rolls, and the third guide (guide F) is tapered in the vertical plane, so as to conduct the wire directly into the grooves of the coiling-rolls. One side wall of the opening in this guide is a spring, which holds the assess a rod against the opposite side Wall of the opening and prevents lateral displacement.

So far as concerns the actual relative speed of the two sets of rolls much depends upon their relative sizes. It is the peripheral speed of the second set that must be uniformly greater than that of the first set. Hence the larger the rolls of the second set may be, the less Would be their number of rotations.

Having thus described my invention, l. claim- 1. A Wire-rolling machine comprising in its construction a pair of vertical positivelydriven reducing-rolls, an entrance -guide therefor, a second pair of horizontal positively-driven reducing-rolls, a guide between the two pair of rolls, means for automatically adjusting the speed of one pair of rolls to prevent the Wire from being drawn by one pair or forced by the other pair, a coiling device, and a guide between the second pair of rolls and said coiling device.

2. A Wire-rolling machine comprising in its construction the vertical positivelydriven rolls 9, the entrance-guide therefor consisting of the trough 27 having rolls 26, the horizontal positively-driven reducinga'olls 16, the taperin g guide E between rolls 9 and 16, means for automatically adjusting the speed of one pair of rolls to prevent the Wire from being drawn by one pair or forced by the other pair,

of a pair of driven rolls intermediate the first I rolls and the ceiling device, and driven at a higher speed than the first rolls, for the purpose set forth, a guide tapering in the hori- Zontal plane by which the Wire is conducted from the first rolls to the second rolls and a guide tapering in the vertical plane by Which the rod is conducted from the second rolls to the ceiling device.

The combination with a pair of driven reducing-rolls, and driven grooved coilingrolls, of a pair of driven reducing-rolls intermediate the lirst rolls and the coiling rolls and driven at a higher speed than the first pair of rolls, for the purpose set forth, a guide E which conducts the rod from the first rolls to the secon d rolls and a guide ll one of Whose side Walls is a spring by which the rod is conducted to the grooves in the coiling-rolls.

In testimony whereof I aflix my si nature in presence of two Witnesses.
